Band 5+: You are going to teach English to your friend's child. Write a letter to your past English teacher to ask if you can borrow some books from him/her. In your letter tell your teacher about the child; say when and where you will teach the child; explain what books you would like to borrow.

The letter addresses the main task requirements: it mentions the child (Thom, age 7, elementary school), the teaching schedule (twice a week, Sunday and Friday, 7-9 pm), the location (friend's house), and the type of books needed (illustrated, beginner-friendly workbooks). However, there are some inaccuracies and omissions that affect clarity and task achievement. For example, the phrase 'I would borrowing' is grammatically incorrect, and 'I would be grateful if you could' is incomplete. Additionally, the letter does not clearly specify the exact books or topics (e.g., grammar and vocabulary) in a detailed way, and the request could be more polite and specific. To improve, ensure all sentences are complete and grammatically correct, provide more precise details about the books (e.g., titles or levels), and make the request more courteous and explicit. Also, avoid informal phrasing like 'Hope you are doing well' in a formal letter to a teacher.

The letter has a logical structure with clear paragraphs, but the flow is sometimes disrupted by awkward phrasing and unclear references. For example, 'I would borrowing some books that has some illustrate and beginner-friendly workbook' is confusing. The closing is also incomplete ('I would be grateful if you could.') and should be finished. To improve, ensure each paragraph has a clear topic and use cohesive devices (e.g., 'Firstly', 'In addition', 'Moreover') to link ideas more smoothly.

The vocabulary is adequate for the task but lacks range and precision. Some word choices are incorrect or informal (e.g., 'elevate his English skills' instead of 'improve', 'has a good basic skills' instead of 'has good basic skills', 'illustrate' instead of 'illustrations'). To improve, use more precise and natural vocabulary (e.g., 'enhance', 'workbook with illustrations', 'beginner-friendly materials') and avoid repetition. Also, use appropriate formal language for a letter to a teacher. Boost vocabulary complexity to elevate the overall score.

There are numerous grammatical errors that affect clarity. Examples include: 'I am contacting you to asking' (should be 'to ask'), 'his seven years old son' (should be 'seven-year-old son'), 'has a good basic skills' (should be 'has good basic skills'), 'I would borrowing' (should be 'I would like to borrow'), 'that has some illustrate' (should be 'that have illustrations'), 'return it' (should be 'return them'), 'The tutor would be assign' (should be 'The tutoring would be assigned'), and 'at my best friend house' (should be 'at my best friend's house'). To improve, review basic grammar rules, especially verb forms, pluralization, possessives, and subject-verb agreement. Practice writing with more complex sentence structures while ensuring accuracy.
